As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues.

The issues that could not be resolved during this revision will be debated for the next jso and these are:. It is my pleasure to announce that the fourth edition of ISO — Specifications of marine fuels- and ISO — Classification of marine fuels- will be 8126-1 on the 15th of June and available on the ISO website www. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection.

Engine manufacturers are in the process of reviewing their limits to this value. A fuel shall be considered to contain ULO when either one of the following conditions is met: It is important to us that you purchase the right document. There were a number of lengthy debates within the Working Group.

As the scope of ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled out. From the specification writers point of view it is hard to describe the enormity of the task at hand. As a non-governmental organisation ISO has no legal authority to enforce standards implementation.

The CCAI limit included in the marine fuels standard is there to prevent abnormal or peculiar fuel blends from finding their way into the market. The basis for including CCAI was as a substitute for a minimum viscosity limit. However, because of its potentially fatal nature, operators of fuel storage terminals have prevented H2S from entering the supply chain system. ISO standards are normally revised every 5 years.

Notify me of new comments on this article. International Classification for Standards ICS is an international classification system for technical standards.

ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva. WG6 aim is, whilst considering the safety, health and environmental issues, to take into consideration both technical and commercial aspects impacting the marine industry and isoo the impact of the specification limits to ensure world-wide fuel availability.


These are factors that are beyond the control of the supplier of the fuel. For other products, such as biomass to liquid BMTL and hydrotreated vegetable oil Ixothe WG maintained that these shall be considered as a separate issue for discussion during the next revision of the standard. Achieving universal agreement on contentious issues connected with today’s marine fuels is a good achievement, which was not easy.

The technical work is carried out through technical committees — abbreviated as TCs. The most important reason and benefit of measuring H2S in liquid phase is that it deals with the key issue, which is to measure the potential latent H2S concentration of the fuel oil that could be released over a period of time from a bunker fuel at any suitable conditions, when the fuel is transferred, heated and agitated by the rolling action of the ship, rather than the measurement of variable equilibrium dynamics of the vapour phase.

The experiences gained with operation on low sulphur fuels, air quality, ship safety, engine performance, crew health as well as operational aspects and other changes of the bunker market realities were the main drivers for WG6 work and the agreed changes considered necessary were introduced into the standard.

Categories of marine fuels This document has been re-assessed by the committee, and judged to still be up to date. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. The ISO entitled “Classification of marine fuels” has been revised and now it comprises: Marine fuel standards – the next stage: Furthermore, while biodiesel has proven to be acceptable for use in automotive and truck engines, there are unknowns as to the potential effects of FAME products on the range of marine engines and other equipment i.

Changes for Distillate Fuels only are: For the preparation of the 4th edition, the WG6 met 13 times in 2 years.

ISO 8216-1

ISO membership is open to national standards institutes or other standardization organisations. The wear scar limit was required only 2816-1 a particular form of passenger car fuel injection equipment and therefore not applicable to marine fuel pumps.


In addition, today’s non-marine distillate fuels can contain a significant amount of bio-derived components, which might impact on the oxidation stability of the fuel. The chemistry of residual fuels is probably the most complex of the oil barrel and some of the components of the final blend are rather resultants than controlled fractions. Thus, it should be treated as contamination from the supply chain system.

Since the GTL products are paraffinic hydrocarbons and they are undistinguishable from the rest of the petroleum based marine fuel, no actual reference needs to be made for GTL synthesized hydrocarbons in the scope of the standard. Notwithstanding this, the Working Group acknowledges that whilst H2S should not be present in marine fuels, the current test methodology and the requirements for setting the specification limits cannot guarantee that H2S gas will not be released during the course of onboard storage and handling.

In view of the difficulty of ixo a wording that fuel is free of ULO, the WG agreed that it should be expressed in terms of when a fuel does contain ULO and amend the wording in Table 2 as follows: Another most important consideration is when a supplier delivers fuel 8216-11 a customer, the supplier should measure the presence of H2S in the liquid phase of the fuel in order to provide an indication of the maximum amount of H2S that may emerge from the liquid phase during subsequent handling of the fuel.

We recommend that you check the website of the publishers of the international document before making a purchase. Therefore the measurement of H2S in vapour phase of the test method’s container as a fuel quality parameter could provide a false expectation for safe use, often providing lower than expected results, Such results must be interpreted with due diligence and care as they are not related to the total H2S entrained 826-1 the fuel or cargo. Perhaps we are moving in the direction of higher quality residual fuels suitable for use in the engine without the need to first clean it.
